[mjmartin] 45668: [usb/usbehci] - Add back WorkItem code but use it for calling the hub drivers callback routine (telling hub driver it needs check port status). - Add missing break for case URB_FUNCTION_GET_STATUS_FROM_DEVICE. - RootHubInitNotification: BusContext is the Device Object not the Device Objects Extensions. - UsbEhci now receives URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER IN requests, which is where we want to be for informing hub driver which port a device has been connected.

[usb/usbehci]
- Add back WorkItem code but use it for calling the hub drivers callback routine (telling
hub driver it needs check port status).
- Add missing break for case URB_FUNCTION_GET_STATUS_FROM_DEVICE.
- RootHubInitNotification: BusContext is the Device Object not the Device Objects
Extensions.
- UsbEhci now receives URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER IN requests,
 which is where we want to be for informing hub driver which port a device has been
connected.
